Indicator and warning lamps

Technology that monitors itself

Indicator and warning lamps identified
by "

l

" are tested for proper operation
whenever the ignition key is turned.
They each light up once for different
periods of time.
The indicator lamps signal defects in
monitored systems by either remaining
lit after the engine is started or by
coming on in the course of normal
vehicle operation. Refer to the following
section for detailed information on how
to respond to the various types of warn-
ings.

Red: stop immediately

Battery charge current
The battery is no longer being
charged. Indicates a defect in
the alternator drive belt or the charging
circuit. Please contact the nearest
BMW center.
Never attempt to continue driving
if the drive belt is defective: the
engine could overheat and sustain
serious damage. A broken or damaged
drive belt will also lead to a sudden
increase in steering effort.

<

Engine oil pressure

l

Stop vehicle immediately and
switch off engine. Check the
engine oil level and top up as required.
If the oil level is correct, please contact
the nearest BMW center.
Do not continue driving. The
engine could sustain damage
owing to inadequate lubrication.

<



Flat Tire Monitor

l
Flashing warning lamp in addi-
tion to an acoustic signal: a flat
tire has occurred. Carefully reduce
speed to less than 50 mph (80 km/h),
and avoid hard braking or steering
maneuvers.
For additional information, refer to
page 67.
Brake warning lamp

l

If the lamp comes on when the
parking brake is not engaged,
check the brake fluid level. Before
driving further, be sure to read the
notes on pages 92 and 114.

dian models.

Indicator and warning lamps

Red and yellow: continue driving
cautiously

The red brake warning lamp
comes on together with the
yellow indicator lamps for ABS
and DSC:
The entire ABS, CBC, DSC and
DBC control system has failed.
Continue driving cautiously and
defensively. Avoid hard brake
applications. Please have the
system checked by your BMW center
as soon as possible.
For additional information, refer to
pages 65, 88.

belts are fastened.
For additional information on safety
belts, refer to page 50.
Airbags

l



Please have the system
inspected by your BMW center.
For additional information, refer to
pages 51, 150.

Yellow: check at the earliest
opportunity

Antilock Brake System (ABS)

l

ABS has been deactivated in
response to system malfunction.
Unrestricted conventional brake system
performance remains available. Please
have the system inspected by your
BMW center.
For additional information, refer to
page 88.

models.
Engine oil level
Comes on while driving: the oil
level is at the absolute
minimum; add engine oil as soon as
possible. Do not drive more than
approx. 30 miles (50 km) until you add
oil.
For additional information, refer to
page 111.
Engine oil level
Comes on after the engine has
been shut off: add engine oil at
the earliest opportunity (when you stop
to refuel).
For additional information, refer to
page 111.

Coolant temperature gauge Service Interval Display BlueThe engine is still cold. Drive at
moderate engine and vehicle speeds.RedWhen you switch on the ignition, the
warning lamp comes on briefly to
confirm that the system is operational.
If the lamp comes on in the course of
normal vehicle operation, the engine
has overheated. Turn it off immediately
and let it cool down.520de031
Between the blue and red zonesNormal operating range. It is not
unusual for the needle to rise as far as
the edge of the red zone in response
to high outside temperatures or severe
operating conditions.
For checking coolant level, refer to
page 113.
Remaining distance before
serviceThe displays shown in the illustration
appear for a few seconds when the
ignition key is in position 1 or after the
engine is started.
The remaining distance in miles and the
next scheduled service will appear
together with the display OILSERVICE
or INSPECTION.
The computer bases its calculations for
the remaining distance on the previous
driving style.
A flashing display and a "Ð" in front of
the number indicate that service is past
due by the number of miles displayed.
Please contact your BMW center for an
appointment.520us006

Wheel and tire combinations The right choice
Use only wheels and tires
approved by BMW for the corre-
sponding vehicle model, as otherwise
the tires may make contact with the
body as the result of tolerances despite
the same nominal size being used,
resulting in serious accidents. If non-
approved wheels and tires are used,
BMW cannot evaluate their suitability,
and therefore cannot be held liable for
driving safety.<
For wheel and tire specifications
approved by BMW, refer to page 104.
The correct wheel and tire combi-
nation affects different systems
that otherwise will not function prop-
erly, e. g. ABS, DSC and Flat Tire
Monitor.
For this reason, use only tires of the
same brand and tread pattern on the
vehicle and, for example, restore the
approved wheel and tire combination
following a flat tire as soon as
possible.<
Codes on tires and wheels The code on tires has the following
meaning.
Codes on radial tires:
The speed rating indicates the
approved maximum speed for the tire.
Summer tires:
S = up to 112 mph (180 km/h)
T = up to 118 mph (190 km/h)
H = up to 130 mph (210 km/h)
V = up to 150 mph (240 km/h)
W = up to 167 mph (270 km/h)
Y = up to 186 mph (300 km/h)
ZR = over 150 mph (240 km/h)
Winter tires:
Q M+S = up to 100 mph (160 km/h)
T M+S = up to 118 mph (190 km/h)
H M+S = up to 130 mph (210 km/h) For example:
Nominal width
in mm
Aspect ratio in X
Radial tire code
Rim diameter in inches
Load rating
(not on ZR tires)
Speed rating
(before R on ZR tires)
245/45 R
1896W
Codes on light-alloy wheels:
Protect tire valves from dirt by using
screw-on valve stem caps. Dirt in the
valves frequently leads to slow leaks.
Safety tires carry additional designation
codes; these vary according to manu-
facturer:
Bridgestone RFT
Dunlop DSST
Goodyear EMT
Michelin ZPStorageAlways store tires in a cool, dry place,
protecting them against light whenever
possible. Protect the tires against
contact with oil, grease and fuel. For example:
Rim width
in inches
Code letter for
flange type
Symbol for full-drop
center rim
Rim diameter in inches
Hump on the 2 rim shoulders
8 x 18 EH2

Engine oilChecking the oil level 1. Park the vehicle on a level surface
2. Let the warmed-up engine idle for
about 15 seconds, then turn it off
3. Pull the dipstick out after about
1 minute and wipe it off with a clean
lint-free cloth, tissue, or similar mate-
rial
4. Carefully push the dipstick all the
way into the guide tube and pull it
out again
5. The oil level should be between the
two marks on the dipstick.
As with fuel economy, oil consumption
is directly influenced by your driving
style and vehicle operating conditions.520de089
The oil volume between the two marks
on the dipstick corresponds to approx.
1.1 US quarts (1 liter). Do not fill beyond
the upper mark on the dipstick. Excess
oil will damage the engine.520de091
Adding engine oil Wait until the level has dropped to just
above the lower mark before adding oil.
However, never let the oil drop below
this mark.
BMW engines are designed to
operate without oil additives; the
use of additives could lead to damage
in some cases. This also applies to the
manual transmission, differential and
the power steering system.<520de166

112n
Engine oil Specified engine oilThe quality of the engine oil is
extremely important for the function
and life of an engine. Based on exten-
sive testing, BMW has approved only
certain types of engine oils.
Use only approved "BMW High Perfor-
mance Synthetic Oil."
If you are unable to obtain "BMW High
Performance Synthetic Oil," you can
add small amounts of synthetic oil in
between oil changes. Use only oils with
API SH specification or higher.
Ask your BMW center for details
concerning the specific "BMW
High Performance Synthetic Oil" or
"synthetic oils" that have been
approved.<
You can also call BMW of North
America at 1-800-831-1117 or visit this
website: www.bmwusa.com for more
detailed information.
Viscosity ratings Viscosity is the oilflow rating as estab-
lished in SAE classes.
Select the correct SAE class based on
the climatic conditions in the area
where you typically drive your BMW Z8
roadster.
Approved oils are SAE classes
5W-40 and 5W-30.<
These oils may be used for driving in all
ambient temperatures.
